GEORGE J. BIOKNELL, OF BOSTON, MASSACHUSETTS.

IMPROVEMENT N CARPET-LlNiNGs.

Specitication forming part of Letters Patent No. 179,839, dated July 18, 1876; application filed May 5, 1876.

To all whom t may concern:

Be it known that I, GEORGE J. BIOKNELL, Of Boston, in the county of Suffolk and State Ot' Massachusetts, have invented an Improved Carpet-Lining, Of which the following is a specification:

This invention relates to carpet linings; and consists in a carpet-lining composed of a bat of fibrous material and a cover or envelope formed of one or more pieces of paper Or cloth united to forni a tube, the fibrous bator sheet being stitched to but one side of the cover, the stitches uniting the cover and bat passing also through a strip Of paper or cloth` placed on top of the bat, thereby forming additional material in which the stitches may hold, and strengthening the lining.

In this lining the upper surface is not perforated with holes as in other sewed linings, and there is no opportunity for the passage of dirt or dust lthrough the lining.

The drawing shows the lining in cross-section.

The lining is shown as composed ofv two sheets Of paper, et b, united at c d, thereby forming a tubular cover or envelope. The fibrous hat 6 within this cover is attached by rows of stitches j', two or more, with but one side (the under side 2) of the cover, and the stitches also pass rthrough strips of paper g, laid on the top of the bat, these strips serving to strengthen the lining, and affording additional material in which the stitches may hold. The upper surface l Of the envelope it will be noticed is free from holes, and is unattached to the bat, and dirt cannot work through the lining from above; and I also find that with the upper portion loose on the bat the lining is made more elastic tO the tread than when the upper portion l is stitched.

In the manufacture ot' this lining the bat will be delivered through a suitable guide between the two sheets a b, placed on suitable rolls and folded at 3 4, the strips g g will be led from proper spools to the upper surface of the bat, and by means of a sewing-machine the strips, bat, and lower half 2 of the cover will be stitched, as at j', one row of stitches (see left-hand side'of drawing) passing through the holding and lapped edges of a b, and afterthese parts are stitched together the other two edges of (t b are united by pasting, as at d, thereby completing the lining.

1t is obvious that one sheet of paper might be used instead of two, and instead of paper I may employ cloth.

I claim- As a new article of manufacture, a carpetlining composed of one or more covering-sheets made as a tube, and a ibrous hat stitched to one side only of the cover, and provided with strengthening-strips g within the cover, the stitches entering only the strips, the bat, and one side of the cover, substantially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

GEO. J. BIOKNELL.
